  • each of the antennas 1100-1 to 1100-4 of the antenna system 1000 disposed in the vehicle is formed to electrically connect the metal patch 1101 and the ground layer GND of the second substrate S2.
  • a shorting pin 1102 may be further included.
  • the shorting pins 1102 may be formed as a plurality of shorting pins separated by a predetermined angle so as to vertically connect the metal patch and the ground layer GND of the second substrate S2.
  • the cone antennas 1100-1 to 1100-4 may be disposed on the upper left, upper right, lower left, and upper right of the electronic device.
